If I do ldm ls l ldom1
the memory block is as follows:-
MEMORY
RA PA SIZE
0x20000000 0x20000000 64G
0x1420000000 0x1020000000 16G
0x1c20000000 0x1420000000 16G
0x2420000000 0x1820000000 16G
0x2c20000000 0x1c20000000 6G
What are RA/PA? What is total memory allocated? Why split like this?
Memory is split probably due to adding and removing memory from virtual machine, to other virtual machines etc.
They system/hypervisor will try it's best to satisfy your additional memory request with continuous memory space, if possible, if not it will give you free memory present on the system.
PA is physical addresss, as for RA i'm not sure
The LDOM itself will see the cumulative value of those present, 118 GB.
You can check that from the ldom itself via :
echo "::memstat" | mdb -k
Hope that helps
